Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
SpraySelect holds the better App Store score, 5.0 against 3.1. Both are backed by a comparable volume of ratings — 10 and 16 respectively. Written reviews complicate that: 19% of SpraySelect's written reviews are positive against 33% of PowerAssist™'s, so the app with the better star average is not the one people write more warmly about.
SpraySelect ships an update every 4 months, PowerAssist™ every 5 months. The most recent releases landed on June 11, 2026 and September 20, 2026 respectively.
